Overview of the Androstenedione
The Androstenedione blood test measures the concentration of androstenedione, a steroid hormone produced mainly by the adrenal glands and the ovaries or testes.
Androstenedione sits within the body's steroid hormone pathway and acts as a precursor from which other sex hormones, including testosterone and oestrogens, can be produced. Measuring it can therefore provide useful information when androgen production or adrenal and reproductive hormone function is being investigated.
The test contains 1 biomarker: Androstenedione. It may be requested when investigating signs of androgen excess, irregular menstrual cycles, possible polycystic ovary syndrome (PCOS), fertility concerns, early or unusual pubertal development, or certain adrenal disorders.
Androstenedione can be particularly useful when considered alongside other hormones such as Testosterone, DHEA-S, 17-Hydroxyprogesterone, SHBG, LH and FSH. The pattern across several related hormones is usually more informative than one isolated result.
A raised Androstenedione result does not independently diagnose PCOS, congenital adrenal hyperplasia or an adrenal or ovarian disorder. Likewise, a result within the laboratory reference range does not rule out a hormonal condition. Interpretation should consider age, sex, symptoms, menstrual cycle stage where relevant, medication and other endocrine results.
What Does the Androstenedione Test Check?
This test measures 1 biomarker.
Androstenedione
Measures a steroid androgen produced mainly by the adrenal glands and gonads that acts as a precursor to testosterone and oestrogens. The result can provide information about androgen production when investigating hormonal symptoms, PCOS, adrenal disorders or other endocrine conditions.
Who May Benefit From the Androstenedione Test?
This test may be suitable for people whose symptoms or previous hormone results suggest that androgen production requires further investigation.
Possible androgen excess - Androstenedione may provide useful information when symptoms suggest increased androgen activity.
Possible polycystic ovary syndrome - Androgen measurements may form part of the wider hormonal assessment for PCOS, although no single blood test confirms the condition.
Irregular or absent periods - Androstenedione may be considered alongside reproductive and thyroid hormones when menstrual cycles are persistently irregular.
Excess facial or body hair - Hirsutism can be associated with increased androgen activity and may prompt further hormonal investigation.
Persistent hormonal acne - Androgen-related testing may provide useful information where acne occurs alongside other signs of hormone imbalance.
Unexplained scalp hair thinning - Androgen excess is one of several possible contributors to patterned hair loss and should be considered within a broader assessment.
Possible adrenal androgen excess - Because the adrenal glands produce Androstenedione, the test may contribute to investigation of adrenal hormone disorders.
Fertility or ovulation concerns - Androgen abnormalities can accompany some reproductive conditions and may be assessed alongside other fertility hormones.
Abnormal previous hormone results - A targeted Androstenedione measurement can add information when Testosterone, DHEA-S or related markers have been outside the expected range.
How to Prepare
Where repeat testing is being used to monitor a trend, collecting samples under similar conditions can improve comparability.
Do not stop hormonal medication or prescribed treatment simply to alter your test result unless advised by the healthcare professional responsible for your care.
Symptoms and Reasons to Consider the Androstenedione Test
You may wish to consider the Androstenedione test where symptoms suggest altered androgen production or a clinician is investigating adrenal or reproductive hormone function.
Irregular menstrual cycles - Persistently irregular periods may occur with PCOS and numerous other endocrine or reproductive conditions.
Absent periods - Amenorrhoea can have several hormonal and non-hormonal causes and may warrant a broader endocrine assessment.
Excess facial or body hair - Increased coarse hair growth in androgen-sensitive areas can occur when androgen activity is elevated.
Persistent acne or oily skin - Androgen activity can influence sebaceous glands, although acne has many possible causes.
Scalp hair thinning - Androgen-sensitive hair loss may occur in some people with hormonal disturbances.
Difficulty conceiving - Abnormal androgen production can sometimes accompany conditions affecting ovulation and fertility.
Unexpected voice or body-hair changes - More pronounced signs of virilisation warrant clinical assessment and a broader androgen investigation.
Signs of unusually early puberty - Androstenedione may be included in specialist endocrine testing where pubertal development begins earlier than expected.
Previous abnormal Testosterone or DHEA-S - Measuring Androstenedione may help provide additional information about the wider androgen pathway.
Possible adrenal disorder - Androstenedione can form part of the hormonal investigation where adrenal steroid production is suspected to be abnormal.
Androstenedione-related symptoms overlap with PCOS, thyroid disorders, medication effects, menopause, congenital adrenal hyperplasia and other endocrine conditions. Blood testing should therefore be interpreted alongside clinical history rather than used as a stand-alone diagnosis.
Rapidly developing virilisation, such as a sudden deepening of the voice, rapidly increasing facial hair or marked changes in muscle mass, warrants prompt medical assessment because significant androgen excess may require further investigation.
How to Book Your Androstenedione Test
Booking your Androstenedione test with London Blood Tests is simple and designed to fit around your schedule.
Choose the Androstenedione
Select the Androstenedione test online and review the included hormone biomarker before booking.
Select your sample collection option
Choose an in-clinic blood draw (+£35) or a home or hotel phlebotomy visit (+£60) where a qualified phlebotomist collects your sample.
Attend your appointment
A trained professional will collect your blood sample safely and efficiently at the clinic or during your arranged home or hotel visit.
Laboratory analysis
Your sample is sent to the laboratory, where Androstenedione is measured using specialist hormone analysis.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, endocrinologist, gynaecologist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Androstenedione test is approximately 2 business days after the sample arrives at the laboratory.
Results are sent securely by email once laboratory analysis and authorisation are complete. Turnaround therefore begins when the laboratory receives the sample rather than necessarily from the time your blood is collected.
Specialist hormone analysis can occasionally require repeat measurement, additional quality checks or laboratory review, which may extend the expected turnaround.
Understanding Your Results
Your laboratory report will show your Androstenedione concentration together with the reference range used by the analysing laboratory. Expected concentrations vary according to age, sex, hormonal status and laboratory methodology.
A raised Androstenedione result may occur with increased adrenal or gonadal androgen production. This can be seen in conditions including PCOS and some forms of congenital adrenal hyperplasia, but the result is not specific enough to determine the cause by itself.
Substantially elevated androgen concentrations may sometimes lead a clinician to investigate less common adrenal or ovarian causes, particularly when symptoms are severe or have developed rapidly.
A low result may occur with reduced adrenal or gonadal steroid production in some circumstances, but an isolated low Androstenedione measurement does not establish adrenal, ovarian or testicular dysfunction.
The result is often more informative when interpreted alongside DHEA-S, Testosterone and 17-Hydroxyprogesterone. Depending on the clinical question, LH, FSH, Oestradiol, SHBG, Free Testosterone or other endocrine tests may also be considered.
A normal Androstenedione result does not rule out PCOS or another hormonal condition. Diagnosis should take account of symptoms, menstrual history where relevant, other laboratory findings and, when appropriate, imaging or specialist endocrine assessment.
